I t 7 Application filed FehryiaryZL-IQOB. Serialllo.;144,4=l8. (Nomodel.) I V sidingat New Britain, in the county of Hart: ford and.State, of Connecticut, have invented a newfa'nd usefullce-Greepergof'which the designed to be attached; to =a-boot or shoe toThis invention relates tothat class of devices prevent slipping onice orhardened snow. It is the object to provide a structurewhich may bereadily-manufactured, can besecurely Figure .1 is a side elevatiomofgoneof thev structures, indicating the manner-ii'n which it is applied to ashoe.

Inthe structure illustratedin thefirst five figures of the drawings, abase-plate 10 is employed having downturned flanges 11 at its partsinall the figures of the drawends, the edges of said flanges beingserrated" to form rows of teeth 12. This base-plate is preferablyformedof sheet metal and conforms to the shape of the shank of the sole, beingadapted to fit against the same and just in advance of the heel, asindicated in Fig. 1. As there shown, one of the flanges abuts againstthe heel and is somewhat longer than the one located at the front end ofthe plate.

A pair of spaced clamp members 18 are slidably mounted upon the base andcomprise metal strips that extend across the under face thereof andhaving upturned sole-engaging hooks 1 1 at their ends, said hooksextending around and above the side edges of the base- Be it known thatI, CHRISTiAN F'nrn nnicn ,RECKNAGEL, a citizen of the United States, re-

plate The, clamp members are secured; to the base by means of screws 15or other fasf tening devices, which'pass through transverse slots 16,formed in the members. Journaled :between these members is an actuatingand locking device therefor in .tlieform ofa cam.

comprising a plate 17 secured to the base by a suitable. pivot.18 andhaving cam-slots 19 arranged 'on opposite sides of the-pivot; This plateis provided with a handle-lever 17*, by means of which it mayb'eactuated. Project: ing lugsQO, arranged. upon the clamp mem: bers,engage in the slots 19 and bear against the edgesthereofl. An additionallockinthe formof a block 21 is preferably secured to theinner-face ofthe cam-plate and is ellip-; tfi'cal: in form, being located between theclamp members andarrangedto bear against their opposing inner edges, asclearly shown in Figssd and 1. 1 Y i In applying the'deviceto a boot or,shoe the lever is first swung outwardly, whereupon the clamp memberswill be drawn-towardeach other.

The creeper is then arranged against the shank of .=the-sole.,and ,thelever, ;-moved back toen-position. against or contiguous to -the heel-.i'l-"Th-iswillmove. the clamp members away fromeach-ot her and thehooks-thereof will engage thesole-shank'. The block 21 will 1 thus bedis'posed in the position; illustrated in I Fig." 2 and :"serve asadditional locking ,means,,

which will prevent the clamps movingtoward each other and turning thecam-plate.

T In Fig.6 a slightly-modified form ofconstruction is illustrated; Theelements are substantially the same as those above described, with theexception of the clamping members. In this instance said members arearranged longitudinally of the base-plate and are designated by thereference-numeral 13 The terminal hooks 14 of each clamp member'extendfrom the same side of the creeper, and the cam-grooves 19 are so locatedthatfwhen the camis rotated the clamping members will be moved towardeach other, or, in other words, transversely ofthe base-plate. The

action is, however, substantially the same and is as efiective as thearrangement first described.

It will be evident that this structure may be manufactured at smallcost, as the parts can be formed of sheet metal stamped to proper form.The creeper, furthermore, when secured will not slip upon the shoe orboot and will not only prevent slipping upon ice, but will constitute asupport for the instep of the wearer.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In an ice-creeper, the combinationwith abase, having spaced sets ofdepending spurs, of shoe-engaging members movably mounted on one side ofthe base between the sets of spurs and having terminal hooks thatproject above the opposite side edges of the base and engage the shankof the shoe or boot, and means coaoting with the members for moving thesame toward and from-eachother.

2. In an ice-creeper, the combination with a base having downturnedflanges at certain of its side edges, of shoe-engaging members movablymounted on the base and having upstanding sole-engaging hooks projectingabove the other side edges, and a cam journaled on the base and coactingwith the members to move the hooks into engagement with the sole of ashoe and thereby secure the base with the flanges transversely of saidshoel 3. In an ice-creeper, the combination with a base-plate havingdownturned flanges at certain of its opposite side edges, said flangesbeing serrated to form spurs, of shoe-engaging members slidably mountedon the under side of the base between the flanges-and having upstandingsole-engaging books that extend across the other opposite side edges ofthe base and project above the same, a camjournaled upon the under sideof the base between the shoe-engaging members and extending beneath theunder faces of said members, movable connections between the cam andmembers, and a handle carried by the cam and projecting from one side ofthe base, said handle swinging between the corresponding ends of theflanges.

4. In an ice-creeper, the combination with a base having rows ofdepending spurs at its ends, of clamp members slidably mounted on theunder side of the base and extending across the same, said membershaving outstanding sole-engaging hooks projecting over the side edges ofthe base, and a cam journaled on the under side of the base between themembers and coacting with the inner opposing edges thereof.

5. In an ice-creeper, the combination with a base having spurs, ofspaced clamped members movably mounted upon the base, and a revolublelocking device located between and bearing against the opposing inneredges of the clamp members.

6. In an ice-creeper, a base-plate arranged to fit against the shank ofthe shoe-sole, said plate having its end edges downturned to constituteterminal flanges and serrated to provide transversely-disposed rows ofteeth, one of said flanges being of greater width than the other andarranged'to abut against the heel of the shoe, and means for securingthe plate to the shoe. I

7. In an ice-creeper, the combination with a base having downturnedflanges and edges located in angular relation to the downturned flanges,shoe-engaging members having upturned hooks projecting above the saidangularly-disposed flanges, said hooks .being arranged to engage a bootor shoe and maintain the flanges in transverse relation thereto, andmeans for moving the shoe-engaging members.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses. I
